Oakmark Fund: Fourth Quarter 2014

Theme and Background

This section focuses on the long-term performance of the Oakmark Fund (Investor Class) as of December 31, 2014, presenting return data since the fund's inception in 1991 and disclosing its expense ratio. The report aims to provide investors with a historical performance benchmark for the fund to assess its investment value.

Core Thesis

The author's core investment argument is that the Oakmark Fund has achieved significant positive returns over the long term (since inception, 10-year) and medium term (5-year), with the 5-year return (16.17%) being particularly notable, indicating strong performance in the recent five-year market cycle. The expense ratio (0.87%) is at a reasonable level within the industry and does not excessively erode returns. Counterintuitively, although the 1-year return (11.51%) is lower than the 5-year return, the 3-month return (3.64%), when annualized, still exceeds the 1-year return, suggesting that short-term volatility may be smoothed out by long-term trends.

Key Arguments and Data

The report supports its thesis with data across multiple time horizons, with all returns being annualized total returns. Key data are as follows:

Time Horizon	Annualized Total Return
Since Inception (August 5, 1991)	13.27%
10-Year	8.78%
5-Year	16.17%
1-Year	11.51%
3-Month	3.64%

Long-Term Performance: The annualized return since inception of 13.27% far exceeds the 10-year return (8.78%), indicating a significant contribution from early performance.
Medium-Term Surge: The 5-year return of 16.17% is the highest across all time horizons, reflecting that the market environment from 2010 to 2014 was favorable for the fund's strategy.
Short-Term Volatility: The 3-month return of 3.64%, when simply annualized to approximately 14.56%, is higher than the 1-year return of 11.51%, suggesting strong recent quarterly performance, though the 1-year data may be dragged down by earlier periods.
Expenses: The total expense ratio of 0.87% (as of September 30, 2014) is below the average for actively managed funds in its peer group (typically 1.0%-1.5%).

Investment Implications

Value of Long-Term Holding: The annualized return of 13.27% since inception suggests the fund is suitable as a long-term core allocation, particularly for investors with holding periods exceeding 10 years.
Focus on Medium-Term Trends: The 5-year return of 16.17% significantly exceeds the 10-year return, prompting investors to consider the fund's stock-picking ability in specific market cycles (e.g., 2010-2014), though they should be wary of the risk of mean reversion in future returns.
Cost Advantage: The expense ratio of 0.87% is below the industry average, reducing long-term compounding erosion and making it attractive to cost-sensitive investors.
Short-Term Caution: Although the 3-month return is high, the 1-year return is lower than the 5-year return, indicating potentially significant short-term volatility, making the fund unsuitable for short-term trading or market timing.
